and flanged can bodies may be cheaply and rapidly manufactured, and a machine which preferably performs all of said operations practically simultaneously.

The invention furthermore consists in the improvements in the parts and devices and in the novel combinations of the parts and devices herein shown and described 0 claimed.

A machine embodying the invention comprises in cooperative combination, a body former horn furnished with an extension for supporting the formed can bodies in:

position for operating thereon of the flanging, necking-in and heading dies, wings or folding devices for forming the bodies, a seam bumper, a reciprocating, external necking-in die, an internal necking-in die nrounted on the end of the horn extension and cooperating" with the external 1ieckingin' die, a plurality of opening and closing or radially reciprocating beading dies mounted on the end of the horn extension, a reciprocating conveyor for feeding the canbody blanks to the body forming mechanism and advancing the formed can bodies along the horn extension to the necking-in, beading and fianging dies, a pair of reciprocating sectional Hanging dies co iperating with the horn extension, a pair of reciprocating, sectional can body shape. retaining dies also eooperating with the horn extension to prebody ejector.

A. further object of my invention is in the arrz-mgement and disposition of certain structural features which have a direct bearing on the eiiiciency and accuracy of the operations of the machine. One of thesefeatures comprisesthe tension and alinement rods connecting the several frame members constituting the mechanism supports. It is very essential in producing accurate work that vibration be eliminated from the machine and that the alinement and adjustment of the body forming mechanism, the Hanging, and the necking in devices be maintained during operation; otherwise imperfect work, excessive wear of dies and operating. parts and premature fatigue of the metal constituting the frame of the machine leadto short life and unsatisfactory service.

The other feature constitutes the application of yielding devices to the bearings car,- rying' the operating shafts These yielding or cushioning devices are sufficient to hold the shafts in their bearings during all normal operations; but relieve the shafts, connecting parts and frame work from undue and abnormal strains occasioned by overthick, misplaced or damaged stock or from misadjustment.

In the drawing, forming a part of this specification, Figure 1 is a side elevation of a machine embodying the improvements, parts of the machine being; broken away.

Fig. 2 is a horizontal longitudinal section, taken substantially onihe line 2-2 of Fig.

Fig. 5 isa transverse, vertical section, taken on the line 5-5 of Fig. 1. Fig. 6 is an enlarged, detail end view of the horn extension, apart of the internal necking-in die being broken away. F ig. 7 is a longitudinal, partial section, upon an enlarged scale, of the end of the horn extension, taken on the line 77 of Fig. 6, and showing also the external necking-in die and the Hanging and shape retaining dies, and Fig. 8 illustrates a modified form of necking-in mechanism.

in the drawings, 10 represents a suitable base adapted to su port thevarious parts of the mechanism. iounted on the upright 11 is a'body former horn 12, and adjacent thereto are wings or folding arms 13 adapted to bend the previously hooked body blank around the horn, said wine's 13 being operated by rods 14 and lever 15 keyed to an oscillating shaft 16. Cooperating with the folding arms or wings13 is a bumper 17 adapted to compress the seam 1n the can body, said bumper being operated from a.

5 hooked can body blanks from the edging mechanism (not shown) is a conveyer 20,

provided with fingers 21 adapted to recipro-- cate the blanks from the edging mechanism to the body forming devices, and from the body forming devices to the Hanging, necking-in and beading stations. The horn 12 is provided with an extension 22, which may be formed either separately from or integral with the body former horn 12. The

16 can body supporting horn or. extension 22 is provided at its outer end with an internal necking-indie 23, secured to the extension in any suitable manner, as by means of bolts 24. The diameter of the internal necking-in die 23 corresponds to the desired-internal diameter of the necked-in portion of the can body. Also mounted on the end of the can body supporting horn-22 are radially reciprocating beading dies 25, adapted to move 25 inwardly and outwardly and operated by means of a wedge 26, having a plurality of faces 27 corresponding to the number of sectional beading dies 25, said wedge 26 being normally outwardly pressed by means of a 80. spring 28 seated in a pocket 29 in the horn extension 22. Each of the heading dies 25 is yieldingly held in position by means of a spring 30, seated in a groove 31 formed partly in thehorn extension 22 and partly in the member 25. The horn extension 22 is furthermore provided with a. circumferentially extending groove 32, in which are adapted to be seated a pair of oppositely reciprocating fianging dies 83, each provided with a groove 34 and a limiting wall 35'.

Each of these flanging dies 33 is mounted upon a reciprocating slide 36, slidabl mounted in ways 37, and operated througi means of a link 38 and lever 39 keyed to 4 shaft 40, each of said shafts 40 being oscil-- lated-by'means of a bell crank 41, said bell cranks being connected together by a link 42, and one of said bell cranks 41 being oscillated by a link 43, pivoted to a crank arm 44, keyed to an oscillating shaft 45. Also mounted on eachof the slides 36 is a sectional mold or die 46, conforming in shape to the can body being operated upon and adapted to engage the outer side of the can body during the flanging, heading and necking-in operations and retain the body in its proper shape and prevent buckling during.

the .flanging and necking-in operations. Each of the dies or molds 46 is furthermore provided with a recess 47 to provide clearance for the flange formed on the can body. Each of the molds or dies 46 is furthermore provided near its outer edge with a groove or recess 48, adapted to cooperate with the I beading dies 25. A horizontally reciprocating slide 49 is located in line with the end of the body former horn extension, and has mounted thereon an external nccking-in die 50, the same being provided with a curling die portion 150, when desired and adapted to cooperate with the internal necking-in die 23, said die 50 being secured to the slide by means of a hollow sleeve '51 and nut 52. Mounted in the external necking-in die or plunger 50 is an ejector 53, operated by means of a plunger 54 secured thereto, said ejector 53 being normally retained within the die 50 by means of a spring 55, engaging a washer 56 on the plunger 54. The inner end of the plunger or rod 54 is also adapted to operate the wedge 26, and to thus move the beading dies 25 outwardly. The

ejector-53 is operated by means of a lever 57, pivoted to the slide 49 and adapted to be engaged by an adjustable stop 58 on a stationary part of the machine. The slide 4.) is reciprocated from a crank 59 on a cross shaft 60, said cross shaft (30 being supported in a plurality of yieldingly mounted bearings 61. By providing these yieldingly mounted bearingstil, the machine automatically accommodates itself to various lengths of can bodies without destroying any of the necking-in or flanging dies. The cross shaft 60 is operated from a longitudinally extending shaft 62, which derives its power from the cross shaft 19 through means of a diagonally disposed shaft 63. Mounted on the shaft (30 is a cam 64, having a cam groove 65 therein, adapted to 0p erate and oscillate the shaft 45 through means-of a lever 66 keyed thereto, and having a roller 67 engaging in the groove 65.

The machine is furthermore provided with a chute 68 located adjacent to the end of the body former horn extension. In the modified form shown in Fig. 8, the body former extension 69 has formed integrally therewith .an internal necking-in die 70,- adapted to cooperate with an external neck-. ing-in die or plunger 71, provided with a.

curling die portion 171, in this form the beading dies being omitted.

In the operation of the machine, a hooked or edged blank is fed by the reciprocating feeder to the body forming mechanism where the can body blank is formed into a body and the seam bumped, after which the can body'is pushed along the horn extension to a point beyond the fianging dies, while the latter are in their outermost or open-position, after which the flanging dies are moved inwardly into engagement with the groove in the horn extension. The slide carrying the external necking-in die is then reciprocated toward the horn and the ejector plate 53 within the necking-in die will thereupon engage the outer edge of the can body and push thesame against the flanging dies, thereby forming a flange and at thebeading dies,

same time the beading dies Will be operated by means of the plunger 54 engaging the Wedge 26, so that all three operations of flanging, necking-in and beading are accomplished practically simultaneously. After these operations, the flanging dies and die molds are Withdrawn and the necked-in can body Will be pulled from the horn extension by the external necking-in die and Will be ejected therefrom when the lever 57 engages the stop 58, whereupon the can body will drop down into the chute 68.

The machine as shown is "adapted to operate on cylindrical can bodies, but it will be obvious that the same may be easily adapted to operate on can bodies of other forms. The drawing illustrates one form of the invention, but it Will be understood that the same is merely illustrative, and that many changes and variations may be made in the various parts and details thereof without departing from the spirit of the invention, and all such changes and modifications are contemplated as fairly fall Within the scope of the appended claims.
